SPECIFICATION forming part of Letters Patent No. 607,323, dated July 12, 1898.

' Application filed April 2, 1898. Serial No. 676,208- (No model.)

To all whom it may concern:

Be it known that I, JAMEs W. ANDERSON, of Philadelphia, (Paschalh) in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Cornice-Ladder, of which the following isa full, clear, and exact description.

The object of my invention is to provide a ladder especially adapted to be hung from a cornice and which will be light, durable, and capable of ready application by a single in dividual.

Another object of the invention is to provide the ladder with a platform and the platform with adjustable fender-rails, and, furthermore, to provide the fender-rails with an adjustable and removable guard-rail.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which is represented a perspective View of the improved ladder applied toa cornice.

A footboard A is secured upon horizontal members 1O of the side rails 10 of an upright ladder B. The uppermost step or rung 11 of the ladder is preferably placed at the extreme upper ends of the rails, the lower step or rung of the ladder being readily accessible from the said footboard. Grapples O are provided for the ladder. Each grapple consists of a hook-section 12, adapted to pass over and receive the cornice of a building, and a shanksection 13. The shank-sections of the grapples are preferably flattened and are firmly secured to the side rails of the ladder, usually at the front upper portions of the said side rails. The horizontal members of the ladderrails and the footboard constitute a platform.

In order that the attachment between the ladder and the platform may be as strong as possible and yet the structure be rendered light, metal braces 14 are secured to the platform near its forward edge and to the front face of the rails of the ladder, the attachment between the braces and platform being through the medium of long screws or bolts, which are passed through the footboard and members 10 of the platform.

In connection with the ladder and platform two fender-rails 1 5 are used. Each fenderrail is provided with a longitudinal slot 17, and guide-pins 18 are passed loosely through the slots 17 and through the side rails of the ladder where the horizontal members 10 are mortised thereto, the pins being prevented from leaving the platform by riveting them in place or by other suitable means. Under this arrangement the guide-pins serve also to strengthen the connection between the ladder and the platform.

A threaded bolt or rod 19 is secured to each member 10 of the platform near the front. These threaded rods or bolts extend out loosely through the slots 17 in the fenderrails, and each bolt or threaded rod 19 is provided with a nut 20 at its outer end, enabling the fender-rails to be held firmly in the position to which they may be adjusted.

It is frequently desirable to employ a guardrail 21 in connection with the fender-rails. In such an event the guard-rail extends across the upper portion of both fender-rails at the rear and is fitted into recesses 22, made in the upper edges of the fender-rails. These recesses are provided with pivoted cover-plates 23, and when the guard-rail is in position on a fender-rail and has been properly adjusted it is held firmly in place by set-screws 24, Which bind the front ends of the cover-plates to the fender-rails.

A rearwardly-extending arm 25 is usually formed at each end of the guard-rail, so that the body of the guard-rail will not touch the building, the extensions 25 only having abearing upon the structure. The guard-rail when employed adds to the stability of the device, since it affords a wide bearing for the ladder, and the guard-rail is especially useful when the ladder is to be hung in front of v claim as new and desire to secure by Letters Patent- 1. The c0n1bination,with a ladder, grapples secured to the upper portion of the ladder and a platform attached to the lower portion of the ladder, the said platform consisting of horizontal extensions from the side rails of the ladder, and a footboard secured to the said extensions, of fender-rails provided with longitudinal slots, guide-pins passed through the slots of the fender-rails and through the platform Where it connects With the ladder, bolts attached to the platform near its forward end and extending through the slots in the fenderrails, nuts for the said bolts, a guard-rail supported at the rear portions of the fenderrails, and means for locking, the guard-rail to the fender-rails, substantially as described.

2. The combination of a ladder having means at its upper portion by which it may be suspended, a horizontal platform secured to the lower portion of the ladder and at one side thereof, two fender-rails located respectively at each side edge of the platform and adjustable horizontally, the fender-rails eX-' JAMES \V.
